Android(安卓)调用系统摄像头

在开发android 应用的时候我们经常需要用到摄像头来进行拍照或者是录制视频，这里介绍一种最简单的方法：调用系统摄像头来拍照，并将照片保存起来
启动摄像头的方法：

startActivityForResult(new Intent("android.media.action.IMAGE_CAPTURE"), TAKE_PICTURE);

拍摄成功后接收参数的接收方法我们只需要重写

protected void onActivityResult(int requestCode, int resultCode, Intent data)方法即可 如： final int TAKE_PICTURE = 1;protected void onActivityResult(int requestCode, int resultCode, Intent data) {  if (requestCode == TAKE_PICTURE) {    if (resultCode == RESULT_OK) {      Bitmap bm = (Bitmap) data.getExtras().get("data");      imgPhoto.setImageBitmap(bm);      sdCardExit = Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);      if (sdCardExit) {        myRecAudioDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+ "/custom_picture");        if (!myRecAudioDir.exists()) {          myRecAudioDir.mkdir();        }      } else {        mMakeTextToast("", true);      }      try {        File f = File.createTempFile(strTempFile, ".jpg",myRecAudioDir);        BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(f));        photoPath=f.getPath();        bm.compress(Bitmap.CompressFormat.JPEG, 80, bos);        bos.flush();        bos.close();       } catch (FileNotFoundException e) {                                                e.printStackTrace();      } catch (IOException e) {                                                e.printStackTrace();      }    }  }}
